Comet Lovejoy
Astronomers were excited in December 2011, when Comet Lovejoy swept right through the sun #39;s corona with its long tail streaming behind it. NASA #39;s Solar Dynamics Observatory (SDO) captured images of the comet, showing how its long tail was buffeted by systems around the sun, offering scientists a unique way of observing movement as if they #39;d orchestrated the experiment themselves. Since comet tails have ionized gases, they are also affected by the sun #39;s magnetic field, and can act as tracers of the complex magnetic system higher up in the solar atmosphere.
